Dad's genome more ready at fertilization than mom's is—but hers catches up
Researchers from Huntsman Cancer Institute (HCI) at the University of Utah have discovered that while the genes provided by the father arrive at fertilization pre-programmed to the state needed by the embryo, the genes provided ...

Team discovers how a protein finds its way
(Phys.org) —Proteins, the workhorses of the body, can have more than one function, but they often need to be very specific in their action or they create cellular havoc, possibly leading to disease.

Healing by the clock: In fruit flies, intestinal stem-cell regeneration fluctuates with the time of day
Circadian rhythms keep time for all living things, from regulating when plants open their flowers to foiling people when they try to beat jet lag. Day-night cycles are controlled through ancient biological ...

Novel way plants pass traits to next generation found: Inheritance behavior in corn breaks accepted rules of genetics
New research explains how certain traits can pass down from one generation to the next – at least in plants – without following the accepted rules of genetics.

Researchers identify genetic sequence that helps to coordinate synthesis of DNA-packaging proteins
Every time a cell divides it makes a carbon copy of crucial ingredients, including the histone proteins that are responsible for spooling yards of DNA into tight little coils. When these spool-like proteins ...

Assembling the transcriptome of a noxious weed: New resources for studying how plants invade
Life's tiniest architects pinpointed
If a genome is the blueprint for life, then the chief architects are tiny slices of genetic material that orchestrate how we are assembled and function, Yale School of Medicine researchers report Feb. 21 in the journal Developmental Ce ...

Histone modification controls development: Researchers demonstrate that chemical tags on histones regulate gene activity
Every gene in the nucleus of an animal or plant cell is packaged into a beads-on-a-string like structure called nucleosomes: the DNA of the gene forms the string and a complex of proteins called histones forms the beads around ...

Protein paves the way for correct stem cell differentiation
A single embryonic stem cell can develop into more than 200 specialized cell types that make up our body. This maturation process is called differentiation and is tightly regulated. If the regulation is lost, ...
